SECTION 1
GENERAL DESCRIPTIO N
1.1 EQUIPMENT DESCRIPTION
This manual has been prepared to a~sist th~ user in interfacin~, installing, operating and maintaining the REMEX madel RRS7200 punched tape reader/spooler combination. See Figure 1-1. It is the purpose of this model to provide tape reading at up to 200 characters/ second speed along with spooling. Although the applications for punched tape readers are many and varied, they are generally used as input devices for digital computers, communication systems, numerical controls, and system checkout equipment.
The printed circuit card provides the logic control for tape movement in-either direction from external signals. The outputs from the card control a step motor which drives the tape via a -sprocket wheel. Data outputs are generated from the photocell readhead. As tape passes over the photocells, changes in light intensity are sensed by the photocells, amplified, and brought out to an external connector. The card contains the spooler control circuitry and also provides the required power.
The function of the spooler is to payout tape to the- reader and take up the tape that has been read. During read mode, the fully proportional spooler senses the position of the tape arms and provides compensating reel movements that allow the arms to operate near the center of their travel areas.. These movements maintain a constant tape tension across the readhead.
1.2 EQUIPMENT SUPPLIED
Several items are included with the reader-spoolers for spare parts, installation, and maintenance. These items are listed in Table 1-1. No other equipment is required for the operation of the unit.

1.6 MODEL NUMBER DESIGNATION
The REMtx model des:gncs.ion i~ u£@d to code the basic functions and configurations of a particular product line. The model number codes for the RRS7200 are shown in Figure 1-3. An X in a particular digit designator (as used in many parts of this manual, especially in the parts list) denotes any of the combinations for that digit given in Figure 1-3 applies in the instance cited.
Always' consu It the serial number tag for proper voltage and frequency to be used and for model identification. Failure to do so could result in damage to the unit. The serial tag is located on o!,\e of the rear surfaces. In all correspondence, always refer to the complete model number, !ncluding the mode and the special number and the unit's serial number.
The last three digits of the model number denote either a standard unit (000 or 901 and higher) or a special (all other numbers). Units with 000 indicate standard units with no additional options other than those coded in the model number structure. Units with 901 and higher are used to indicate the number of standard options (used only on standard units) which are not coded in the model number. These are listed on the serial tag below the model number in the form of a series of three digit numbers depending upon the number of options used . For example, a unit with 902 would list two three digit numbers. Becuase the list of possible options is constantly changing, it is not included in the manual. Generally, this list consists of special customer requirements that do not affect the operation of the unit and include such things as special paint,no logo, mill edge panel, etc.
1.7 PHYSICAL DESCRIPTION

INSTAlLA TJON AND INTERFACE
2. 1 UNPACKING
To provide the most protection during transit I specially designed and reinforced packing cartons are used to sh ip the REM EX punched tape reader/spoo ler. Those items I isted in Table 1-1 are also packed with the unit. When removing the unit from the carton, the reader-spooler shou Id be lifted with both hands under it. Never lift or attempt to carry. the unit by any of the covers, drive assembly, arms or other delicate parts. Carefully inspect the unit for any apparent damage as soon as it is removed from the carton. Check the equipment supplied list in Table 1-1 against the kit of parts supplied with the reader. In the event the equipment has been damaged as a result of shipping, the carrier and REMEX must be notified as soon as possible .
2.2 MOUNTING
The reader/spooler mounts in a standard 19-inch rack with mounting holes provided. To ensure a minimum transmission of acoustical noise and vibration to other equipment I the reader should be securely mounted. When mounting the unit in a closed cabinet I adequate air circulation should be supplied so that the unit does not exceed the ambient temperature specification listed in Table 1-2.
2.3 IN ITIAl ADJUSTMENTS
Each reader has been accurately adjusted and aligned before leaving the factory. No adjustment or calibaration should be required prior to installation or use . However, the proper fuse from the kit of parts requires installation. Refer to Section 2.4.
2.4 POWER AND SYSTEM CONN ECTIONS
InputAC power (refer to Table 1-2) is applied through the A.C. connector at the rear .
112670-074A
All units come wired for 115 VAC, 47-63 Hz operation. if another voltage isto be used, a wire change on the transformer must be made as described in Section 2.4. 1. In addition, before operating the system , the proper fuse value (as indicated in Table 1-1) must be inserted from the kit of parts. Discard the other fuse (unless, of course, a different voltage operation is ant icipated).
2-1
All control signals and data track output signals are routed through J 1. Figure 2-1 lists the detail routing of these signals and their description is given in Table 3-1. All wire sizes are 22 AWG unless otherwise noted in Figure 2-1. The proper mating connector for Jl has been supplied with the unit.
NOTE: All input and output logic signals are defined for positive logic, mode 5, i.e., logic 0 = OV and logic 1 = +5V. Therefore, signals that are mode 6, OV true for logic 1 (action condition) are written with a bar over the designation, e.g. , Ddve Right Input.

2,4,1 TRANSFO~MfR WIRING CHANGE fOR VOLTAGfS OTHfR THAN ll~ YA~
All units come from the factory with a transformer which allows any of five input voltages to be used: 100, 115, 127, 220 or 240 VAC, 47-63 Hz. Unless othelWise directed by the customer I all units leave the factory wired for 115 VAC. If it becomes necessary to operate on one of the other four voltages, a simple wire change is required.
~ Make sure the power plug is disconnected before making the change.
Power from the AC plug is applied through 51 to TB1-B2 via a white/black wire. See system schematic, Figure 8-2. It is necessary, then to change the white/black wire at T81-82 to TB1-85 for 100 VAC, to TB1-C5 for 127 VAC, to TB1-C1 for 220 VAC or to TBI-Dl for 240 VAC. In addition, the 1-1/2 amp fuse from the kit of parts must be substituted for the 3 amp fuse at F 1 when using 220 or 240 VAC.
2.5 INTERFACE CIRCUITRY
Figure 2-2 illustrates suggested drive and output circuitry with which to interface with the REMEX circuitry. Note the termination network for ~he output signals. This should be incorporated into the user's equipmen~ for maximum noise elimination. Table 3-1 lists which circuit is used with each input or output.
NOTE: All input and output logic signals are defined for positive logic (mode 5), i.e., logic 0 = OVand logic 1 = +5V. Therefore, signals that are OV true (mode 6) for logic 1 (action condition) are written with a bar over the designation, e.g' l Drive Right Input.

3.2 CONTROL FUNCTIONS
Table 3-2 lists the operating controls located on the front panel. A description of the controls and their functions is also included. It is recommended that the reader review the functions of these controls before operating the unit.
3. 3 OPERATING INSTRUCTIONS
The following procedure should be used when loading and reading a tape:
3.3.1 TAPE LOADING INSTRUCTIONS
All units come wired for 115 VAC, 47-63 Hz operation. If another voltage is to be used, a wire change on the transformer must be made as described in Section 2.4. 1. In addition, before operating the system, the proper fuse value (as indicated in Table 1-1) must be inserted from the kit of parts. Discord the other fuse (unless, or course, a different voltage operation is anticipated).
a. Connect J1/P1 and plug the line coreL See Caution in Section 2.4 .
r:=J Steps band c should be performed in the order stated. If step c were performed first (ON-OFF in the ON position with LOOPSPOOL in SPOOL),> the spooler would be enabled and any movement of the tape arms could cause rapid rotation of the hub assembly resulting in possible personal injury.
b. Place the RUN-LOAD switch in the LOAD position.

Raise the Upper Tape Guide allowing tape to be loaded. Install the ree I of tope onto the hub and thread the tope through the speo ler and read head as shown in Figure 3-2. If a loop of tape is to be read I insert it into the reader and let it hang free of the tape arms. Lower the Upper T ape Guide to its closed position.
If a reel of tape is being used I place the SPOOL-LOOP switch in the SPOOL position. If a loop of tape is to be used place the switch in the LOOP position. Place RUN-LOAD switch in the RUN position. This wi" enable the spooler jf the SPOOL-LOOP switch is in the SPOOL position.
Make sure the System Ready output signa I at J 1-14 is in the true cond ition, i.e., O<V<+0.4.
Apply 0<V<+0.4 to J1-10 to select mode 5 data output and data ready signals or +2.4 <V<+5. 0 (or open circuited) to select mode 6. See Section 3.3.6.
The reader may now be operated as described in Section 3.3.2. See Section 3.3.3 for external inhibit operation and Section 3.3.4 for manual drive mode operation and 3.3.5 for wind operation.
To unload tape, stop tape movement, place the RUN-LOAD switch in LOAD I raise the Upper Tape Guide and remove the tape.
To remove power I place the ON-OFF switch in the OFF position.

3.3.2 TAPE DRIVE, ASYNCHRONOUS OPERATION
In this mode of operation, the reader is controlled in either a continuous or a line-at-atime step operation but is not completely synchronized with the reader outputs.
a.
b.
c.
d.
Perform Section 3.3. 1, steps a through g.
Make sure the Data Ready signal at Jl-9 is in the true condition depending upon the mode. See Table 3-1.
Place the Wind Enable input at J 1-18 in its false condition (+2.4 <V<+5.0 or open circuited).
Apply the followine...1Jgnal to the d-:-r-iv-e--:':-ef~t (DL) line, Jl-17 or the drive right (DR) liner J 1-16:
Stop: +2.4<V<+5.0 (2.2K to +5V) or an open circuit Run: 0<V<+0.4@ 5 mAo
The drive signal can be either in the form of a pu Ise or a continuous DC level which must be removed within 440 Ilsec after the leading edge of the true Data Ready Signal to stop on character. A pulse must be maintained unti I the Data Ready signa I goes fa Ise (typ i co lIy less than O. 5 Ilsec). The next pu Ise or DC level may be applied any time after the Data Ready signa I comes true. See Figure 3-1. In this mode of operation tape is driven a nominal 200 characters/sec.
e . If the drive direction is reversed and the spooler is enabled, all drive signals wi" be locked out for 500 ms max. from the time the previous drive signal is terminated to give the servo time to stabilize.
f. Only one run signal must be present at one time. If both run signals are applied simultaneously, the reader will drive in the last previously commanded direction.
3.3.3 EXTERNAL INHIBIT
In this mode of operation, the reader and spooler are inhibited and the System Ready output (Jl-14) and the Data Ready output (Jl-9) are set to the false state. To place the reader in the inhibit mode apply the following signal to pin 15 of Jl:
Reader Not Inhibited: +2.4<V<+5.0 (2.2K to +5V) or an open circuit Reader Inhibited: 0<V<+0.4 @ 5 mAo
3.3.4 MANUAL DRIVE MODE OPERATION
Tape can be driven manually at a nominal 300 characters/sec either to the left or right as fo lIows:
a. Perform Section 3.3.1, steps a through g. 3.3.2 steps a through g or 3.3.3 steps a through g, depending upon the mode.
b. Depress the ¢ switch for drrve left or the Qswitch fordrive right as required. This option cen be used to wind tape onto either reel.

In this mode of operation the winding of the left or right reel at 300 cps can"-be controlled in the following manner:
3.3.6
a. Perform Sect ion 3. 3. 1, steps a throug h g.
b. Make sure the Data Ready signal at Jl-9 is in the true condition depending upon the mode. See Table 3-1.
c. Place the Wind Enable input at J1-18 in its active condition (O<V<+O.4) .
d. ~ the following signal to the drive left (OL) line, J1-17 or the drive rrgflf (DR) line, J 1-16:
Stop: +2.4 <V<+5.0 (2.2K to +5V) or an open circuit Run: O<V<+O.4 @ 5 mAe
In this mode of operation the reader can be used to read (e. g. looking for a stop rewind character) but the reader is not guaranteed to stop on character nor is this mode advisable for step operation.
DATA OUTPUT MODE SELECTION
The output mode of both the data tracks and the Data Ready output is selectable for either Mode 5 (+ 5 volt true) or Mode 6 (0 volt true) by applying one of the following signals to J 1-10:

3.4 OPERA TIONAl MAINTENANCE
After every 6 to 9 hours of use, the operator should check the tape transport area for clean liness. This is extremely important since any dirt or foreign material covering the readhead can cause readout errors. For general cleaning , use the stiff bristle brush supplied. Cleaning pf the photoc:" ass.embly area !s desc.ribed in Section 5~2. 1. 1. Make sure the tape rema ins clean at all tJme;s .slnce a~y residue plcke? up by the tape can be deposited on the readhead . It ~a~ been found In certamcases that residue picked up by the tape comes from soi led hands . It IS Important that care be exercised when handling tape, especially in .machining areas or other areas where grease, oil and sprays are present.

3.6 TAPE PREPARA TlON REQUIREMENTS
Proper tape reader operation requires that the maximum accumulated longitudinal error between feed hole centers in the punched tape be ±O.025 inch within any span of 5 inches, as specified in the American National Standards Institute Standard X3. 18-1967 (ANSI; formerly United States of America Standards Institute). In the event a user has; because of punching problems, a number of tapes which do not conform to this specification by an amount consistently out of tolerance, the reader may be set up as in Section 5.4 using one of these tapes ra ther than the type specified. However I un less absolute Iy necessary, the user shou Id be enco~r~ged not to do this since the reader p~rformance may be comprom~zed, especially in restn ctmg the tape tolerances capab Ie of bemg read. For ease of threading the recommended tape leader length is four feet .
A tape gauge is available from REMEX (part number 110597) so that the ±O.025 to leranc: specification can be checked. To use the gauge, place the feed hole of one end of a 5-mch span (50 characters) at the single cross hair and swing the other end of the 5-inch span in the arc until one of the cross hairs is centered in the feed hole. Read the measurement ad;acent to that cross hair (plus tolerances to the right and minus tolerances TO the left). A second 5-inch gauge is printed at the bottom to check both longitudinal and perpendicular transverse center I ine spacing.

THEORY OF OPERATION
4. 1 BLOCK DIAGRAM DESCRIPTION
The REMEX punched tape reader-spooler combination performs three basic functions: (1) it drives tape in either direction over the read station, (2) converts the tape information into electrical signals and (3) spools tape on and off the tape reels. These three functions are described in block diagram form in Section 4. 1. 1, 4. 1.2 and 4. 1.3 and illustrated in block diagram form in Figures 4- 1 and 4-2. .
4. 1. 1 TAPE DRIVE
Reader Card 11-2461 contains the circuit logic used to operate the stepper drive motor in response to the drive inputs at 200 characters/sec. Refer to Fi~e 4-1 for the Ress;Ler Block Diagram. Applying' a OV, true signal to the drive left (DL) or drive right (DR) input lin~ sets the direction memory in the input logic to the desired state and establishes the direction memory in the input logic to the desired state and establishes the direction of rotation for the motor by setting the three phase counter. The input logic a Iso produces the true Drive Gate (DRVG) signal which triggers the Ready Circuit. It is the function of the Ready Circuit. to make sure the reader is ready to accept a drive command and, when the drive command is accepted, to generate the motor clock pulse (MCP). TheMCP pulse is used to advance the three phase counter one count which steps the motor and, in tum, the tape to left or right one line depending upon the direction previlOusly selected. The tape. then stops on character and waits for the next MCP pulse. The Ready Circuit also locks out the sprocket signal for 2 ms after the MCP is generated so that any initial jitter in the sprocket is locked out as the tape starts up and the sprocket goes off character. At the end of the 1.9 ms time period, the Ready Circuit generates a 400 tJs damping pulse which is applied to all three phases of the motor at once to minimize motor oscillations as the tape comes on character. .
When the next sprocket hole is read, the sprocket output is amplified, delayed 150 tJs and sent to the Ready Circuit. Upon receipt of the sprocket signal, the Ready Circuit generates the following three signals: (1) a Data Ready signal for use in external equipment, (2) c strobe signa I whi ch latches up the data from the read hecx:l and (3) c 440 tJS delay to allow data to be examined and make the stop-go decision. At the end of the 440 tJS delay, if the drive signal has not been removed, the read-drive cycle will be repeated and the tape will advance another line.
4. 1.2 WIND OPERATION . .
In wind mode operation, the Wind Enable line is pulled down to OV wh"ich sets the flipflop FF1. The drive sequence is similcrto that described for tape drive operation with

the following exceptions: (1) the damping pulse is inhibited and (2) after the initial MCP pu Ise starts the motor advancing, a second clock pu Ise is generated CIS soon as the tape goes off character. This sets the three phase counter one count ahead of the line to which the tape is advancing. When that line is reached, the motor will not stop, unless the drive signal is removed, but will continue rotating one line more. Again when the tape goes off character, the counter is again pu Ised. In this manner the counter is always one count ahead of the line being read on the tape. If, during the 440 fJs data sampling period, the reader drive signal is removed, single-shot SS7 is triggered which inhibits the input memory via the Reverse Lock (REV LK) to allow a settling time of 45 ms. SS7 also triggers SS8 causing the counter to back up one count and the motor to stop on character.
4.1.3 READER INHIBIT
The reader can be inhibited by any ~ of three methods: (1) placing the LOAD-RUN switch, 52, in LOAD r causing the LDS to be generated! (2) a true ( OV r rternal Inhibit signal applied to J 1-15. Items 1 and 2 are gated to form the Inhibit (INH . signal which inhibits both the Wind Enable Logic and the Ready Circuit and places the System Ready (SYSRDY) in the false state. The System Ready also goes false if I after receipt of a drive signal r no new sprocket is sensed within 35 ms max, indicating that the reader is out of tape.
4. 1.4 TAPE READ iNG
The readhead is located under the fiber optic light source and contains photovoltaic cells which are used to sense the punched tape perforations. As tape is advanced over the read head I by the sprocket drive, the photovoltaic cells are energized by the light source when the correspond ing ho les are present in the tape. Outputs from the read head are then applied to the data track amplifiers and latch circuits. A true +5V, Strobe signal locks up the two latch circuits, Z2 and Z6, thereby storing that line of data. The latch circuit outputs are applied to the Mode Select gates which produces either mode 5 and 6 outputs depend ing upon the leve I app lied to the Mode Se lect input. At the same time I the Data Ready output signal goes true and it too is gated with the Mode Select signal.
4 .1 .5 SPOOLER BLOCK DIAGRAM
The tape spooler portion of the reader-spooler combination supplies and takes-up tape from the reader during operation. See Figure 4-2 for the Spooler Block Diagram. The operation is discussed below in block diagram form.
Servo mode operation is achieved by the use of an output signal from an arm potentiometer which is proportional to the position of the tape arm. This signal is applied to a summi.ng amplifier which controls a power amplifier that drives the servo motor. When the arm IS
in the center of its trove I the servo motor is not turned on. However I arm movement, caused by the movement of the tape, turns on the motor in the direction which winds or unwinds the tape to bring the arm back to its center position.
4.2 LIGHT SOURCE
A fi lament type lamp rated at 5.0 Vdc is used as the I ight source. It is operated at approximately 15% below rated voltage to provide a long life expectancy. The lamp is
112670-074A 4-3/4-4
mounted in a sleeve at the rear of the front panel. A lens contained in the lamp focuses the light to the fiber optics system which, in turn, conducts the light to the photocells.
4.3 CIRCUIT CARD DESCRIPTIONS
4.3.1 READER CIRCUITRY
The reader c ircui try on PC card 112461 is used: (1) to generate output signals used to drive the stepping motor in response to the drive signal inputs and (2) to provide amp lification and gating of the readhead data output signals .
4. 3 .1.1 Drive Circuits
During the following description, refer to Figure 4-3 which shows the waveforms and timing diagrams for the drive, step and wind operations. This figure is intended as a guide to show the sequence of events and which signals initiate other signals. It must be cautioned that due to the wide range of pulse widths, no attempt has been made to draw the time axis to exact scale. Refer also to the schematic, Figure 8-1, sheet 1, during this description.
Normal operation begins with the loading of the tape. Placing the RUN/LOAD switch (52) in the LOAD position c_auses OV to be applied to Z18-1 and in turn places Z18-3 (the inhibit INH line) at OV. An external inhibifSTgnal applied to Z18-2 produces the same resu It .
The INH signal is applied to Z18-4, Z12-9, and Z22-13 (FF2). The inhibit signal performs the following functions: (1) it clears and inhibits flip-flop FF2, thereby preventing recognition of any srrocket signal, (2) through Z18-6 and Z12-11 it causes the Reader . Ready (RRDY) signa to drop to OV thus ~reventing recognition of the Drive (DRVG) signal, (3) through Z18-6 it places the ata Ready (DATRDY) signal at OV thereby inhibiting data, and (4) through FF2, which is held in the cleared state , and Z16-8, it clears and inhibits SS 1, th\Js preventing recognition of any signal. The inhibit signal is also appI!ed to Z12-9 causing a false System Ready (SYSRDY) to be generated. After the tape has been loaded, placing the RUN/LOAD switch in the RUN position makes the reader operational.
With the inhibiting signals removed, the SYSRDY, DATRDY, and RRD'L.signals are true allowing the drive signal to be recognized. Application of a true OV DL signal at J1-17 sets the directi9n flip-flop, composed of Z10 and Z11, to the drie-Ieft state . This places the clockwise (CW) line at ZlO-ll at OV and the Direction (DRCTN) line at Z15-3 at +5V. A +5V DRCTN signal sets up the three phase counter, composed of FF3, FF4, Z19 to energ ize the motor phases in the sequence which drives the tape to the left, i. e . , phase 3, phase 2 and then phase 1 (drive right is the reverse order). The counter is advanced one count with each clock pulse received from SS2 as described in a subsequent paragraph.
The OV, DL signal also generates the OV true Drive Gate (DRVG) signal at Z9-6 which is used to trigger the single shot 551 at input ~Output 551 then goes to OV which sets flip-Flop FF2, resulting in the negative going FF2 signal which triggers 552 . The SS2 output, in tum, is applied to the three phase counter through Z19-11 causing the counter to step one count .
1 1 2670-074 A 4-7
-A new motor phase is now energized which moves the tape one line to the left. FF2 Qiso CQvses the DATRDY sisnal to 90 false (OV) through Z18-6; FF2 causes the SSYRDY signal to go false (+5V) through 216-6 and Z12-9. ~~2 srays locked in fhe ~et eondition unti I SS 1 times out (approximate Iy 2 ms). As a resu It, any noise or start up jitter from the sprocket signal is prevented from generating a true Data Ready signal.
The positive going edge of the FF2 signal also triggers SS9 which is a retriggerable sing leshot timed for 23 ms. Output SS9 is combined with FF2 to produce End of Tape signal at Z16-6. If SS9 is not retriggered within 23 ms and if no sprocket s~nal is sensed (FF2 remains high) then Z16-6 drops to OV. This places the System Rea y signal at Z12-8 in the + 5V fa Ise state, indicating that the system is not ready.
At the end of the 2 ms period, FF2 is released, but by this time the tape is up to speed and the only signal available to reset FF2is the posit~ going edge of the Sprocket Delay signal from SS4. The positive going edge of the SS 1 signal is used to trigger sing Ie-shot 553. As a result 553 is held at OV for 725 tJS and is applied as a negative OR combination to Z24-13, Z24-4, and Z24-1 causing the remaining two motor windings which are not
. energized during a given phase sequence to become energized for 1 ms. This momentary energ iz ing of a II three motor phases dampens the inherent osci I lations present in a I I stepping motors as the tope moves on character.
When the next line is read I the negative going edge of the Sprocket signa I triggers the 150 IJs Sprocket Delay single-shot SS4. This delay is required when using a feed hole advanced tape to electronically delay the feed hole and make sure all data is latched before the sprocket is recognized. With standard in-line feed holes this serves only to add an extra safety marg in. At the end of the 150 lJS de lay, the posi t i ve go ing edge of SS4 resets FF2. The resulting positive going edge of FF2 is used two places: (1) to trigger single-shot SS5 and (2) to generate the positive going DATRDY signal through Z18-6 (and the OV Strobel and Strobe 2 signals at Z4-2 and Z4-4). The inverse OV, FF2 signal places the SYSRDY signal in the true OV condition through Z16-6 and Z12-8 and Z4-12. The functions of SS5 is to provide a 440 lJS delay by holding the RRDY line at OV. This allows the external equipment to ~amine the data and make the go/no-go decision_ If the decision to stop is mode, the DL input line must be taken high within 440 iJS (actually 490 but conservatively specified at 440 lJs). Otherwise, when SS5 times out 1 the positive going RRDY wi II trigger 5S 1 and repeat the tape advance cycle. If the drive line is taken false and then returned to the true state during the 440 tJs period of 555, 5S5 wiJl be reset by the signal from Z9-8 applied to Z17-3 and the next drive sequence wi /I begin immediately.
4.3.1. 2 Wind Circuits
During normal operation up to 200 cps the Wind Enable line is taken high (or open circu ited). A OV signal applied to Jl-18 and a true drive input cause the reader to wind . tape at a nominal 300 characters/sec. Applying OV to Z13-5 causes Z13-6 to go to +5V and, in turn, Zl4-3 goes to +5V provided the drive signal is present (DRV is +5V at Z14-2). When the first MCP signal is generated, 552 drops to OV and is inverted to +5V at Z13-11. This signal, gated with the +5V at Z13-2, results in Z13-3 dropping to OV and setting flip-flop FF1.
This flip-flop is used to modify the previously described low speed drive sequence by performing the following functions: (1) FFl inhibits the 725 iJs damping pulse S53, (2) FFl enables gate Z16-9 so that as soon as flip-flop FF2 is set by 55}, the FF2 output f
112670-074A
through Z 16-9 clears 55 t and removes the 2 ms hold off, (3) after the first MCP is generated at Z21-12, FF1 at Z18-13 holds Z21-9 low so that the only trigger pulses applied to SS2 is via SS6 (discussed in the next paragraph)are recognized, and (4) ffl enables 5S6 so that it is triggered on the positive going edge of the SPRKT signal.
When the tape moves off character, the positive going SPRKT signal triggers the 1570 ~s one-shot 5S6. At the end of 5S6time, the positive going SS6 signal triggers SS2 which generates a second clock pulse. The clock pulse is also applied to the counter and advances it one count ahead of the phase to which the motor is being advanced. Thus, when the next character is reached, if the reader has not been to Id to stop, the motor wi II continue advancing to the next character without stopping. Each time the tape goes off character, the counter will again be pu Ised causing it to a Iways be one count ahead. It shou Id be noted that after the initial MCP is generated by FF2 going low, FF2 does not generate any more MCP pu Ises on subsequent lines since Z18-13 is held low. This coupled with the absence of the motor damping pu Ise SS3 allows the reader to drive tape in excess of 300 characters/sec.
If, during the period that FF2 is set, the drive signal is removed, the DRV signal will drop to OV and trigger single-shot SS7. The resulting negative going SS7 performs the following functions: (1) provides a 45 ms inhibit to the REVLK line and therefore to the drive logic which allows the motor to settle before the next drive signal is recognized, (2) reverses the DRCTN line at Zl5-3, (3) triggers single-shot SS8, and (4) inhibits any drive signal at Z9-5. With the DRCTN line reversed, the negative going SS8 signal causes the three phase counter to back up one count which puts it in phase with the existing motor position, causing it to stop. SS8 is also used to reset the High Speed flip-flop FF 1. When 5S7 times out, the REVLK signal returns to +5V and the reader is ready to accept the next drive signal.
4.3.1.3 Tape Reading Circuits
Nine photovoltaic cells in the readhead assembly sense the perforations in the tape. Refer to Figure 8-1, sheet 2. An illumination system consisting of a lamp and fiber optics provides a continuous beam which covers the area of the photocells. The tape is driven over the top of the photoce II b lock and when a ho Ie appears between the photoce II and the I ight source, the photoce II becomes energ ized.
Each cell output is applied to an amplifier-latch circuit, Q 1-Q8, Z2 and Z6. Track 1 is used in the following discussion since it is typical of tracks 1-8 (the Sprocket signal is deve loped differently as described in a subsequent paragraph). When track 1 becomes energized, the negative going signal at the cathode of the photocell turns off Q1. Q1 is interconnected with the D3 input and Q3 output of Z2 in a manner which allows Q1 and the first stage of Z2 to function as a Schmitt trigger. Z2 follows all changes in the photocell output until the OV strobe 1 signal (see Section 4.3.1. 1) is generated which locks up Z2 .
Track 1 output at 03 is +5\1 true and is gated with the Mode Select signal at Z3-1 and 2. A OV Mode Select input provides a mode 5 output at J 1-1 (i. e., OV for no hole and + 5V for hole). Conversely I when the Mode Select signal is + 5V, J 1-1 wi II produce a Mode 6 output (i. e., + 5V for no hole and OV for hole). The DATRDY output is gated in the same manner as the track outputs at Z15, pins 4 and 5.
The sprocket track is somewhat different than the other eight tracks in that its Schmitt trigger uses an inverter, Z4, rather than part of a latch and is independent of either the
112670-074A 4-9
Strobe or DATRDY signals. See Figure 8-1, sheet 1. It is also used only as an internal logic signal and is not gated with the Mode Select signal. Both the SPRKT and SPRKT signals are generated and used in the internal logic.
4.3.2 SPOOLER CIRCUITRY
The spooler circuitry is designed to control the payout and take-up of the spooler motors during.5>peration of the unit. Since there are two identical spooler motors and two identical control_circuits only one side will be discussed. The following discussion pertains to the left side (refer to Figure 8-1, sheet 3) during the following description.
In operation, the RUN/LOAD switch is set to the LOAD position (see Figure 8-1, sheet 1) while the tape is loaded on the unit. This generates the Spool Inhibit (SPlINH) signal which is applied to Q16 (Figure 8-1, sheet 3). This in turn causes Q16 to clamp the inpLits to Z27-3, the base of Q19 and the base of Q20 to a bias condition such that the motor drive transistors Q103 and Q014 produce OVat their collectors. This condition
. produces OV across the spooler motor M3 regardless of the position of the left arm potentiometer during the tape loading operation.
After the tape is loaded, the RUN/LOAD switch is p laced in the RUN position, thereby removing the SPLINH signal. The tape arm potentiometer is now the controlling component for the motor control circuit. Assume for the purposes of this discussion that the tape arm is in the slack position. This wi II make the center arm of the potentiometer more positive and this positive voltage is applied to Z27-2 causing the operational amplifier output at Z27-6 to go in the negative direction. The negative going output of the operational amplifier tends to fum Q20 on while Q19 tends to turn off. When Q20 goes into conduction its collector goes in the positive direction and this in tum turns Q104 on, causing Q104's collector to move in the positive direction. At the same time Q19 is tending to conduct I~ss and the Q19 collector goes in a positive direction, allowing Q103 to begin to turn off . The result is the negative going direction of the collector of Q 103 and Q 104. The motor M3 drives in the direction required to take the slack out of the tape and the tape arm is consequently moved to its center position. This reverses the offcenter bias condition described above and the jUDction of the collectors of Q 103 and Q 104 moves toward zero. Since the purpose of the circuit and motors is to maintain a slight tension on the tape, a slight negative voltage remains on M3, sufficient to main-tain the proper tension.
When the tape reader sprocket moves the tape in a direction that tightens the tape the process described is reversed, Q103 and Q104 collectors are driven in a positive direction, and M3 thus runs in the direction required to payout tape.
4.3.3 POWER SUPPLY
The power supply provides the regulated DC voltages required to operate the logic, the spoo Jer dri ve ci rcu its and the spoo ler motors. The major components of the powe r supp Iy consists of power transformer T 1 (Figure 8-1, sheet 3), bridge rectifier BR 1 T main fj Iter capacitors C 102 and C 103, and the output regu lators Z 10 1 and Z 102.
The transformer is a step-down transformer designed to convert the AC line voltage to approximately 33 VAC. The transformer is provided with a tapped primary winding to accomodate a variety of input voltages. The voltage from the transformer secondary is
4-10 1 1 2670-074A
rectified by BRl and filtered by C102 and Ci03. The resultant + 15 and -15 Vdc is used !o provide power to the spooler circuit and motors. The + 15 Vdc is also applied to the mputs of the 5V regulators Z101 and Z102. Z101 provides regulation of the 5 Vdc logic power while ~102 provides the regulated voltage for the reader lamp. Z101 is not adjustable and provIdes regulated 5 Vdc for the logic circuitry. Z 102 is provided with a voltage level adjustment R63 for varying the lamp brilliance . . This makes it possible to adjust the lamp voltage to approximately 4.3 Vdc thereby extending lamp life expectancy. The lamp voltage shou Id not be adjusted higher than 4.7 Vdc .
4.4 MECHANICAL THEORY OF OPERA TION
4.4. 1 TAPE TENSION
Tape hand ling, at all speeds, requires that the proper tape tension be maintained. This is especially true where rapid, hi-torque starting, reversal of direction, and stopping is necessary. For example, in order for the tape to be moved over the readhead in a sfartstop "geneva" mechanism fashion, the tape must have a certain tension applied in order to flow smoothly.
Assume that a full reel of tape is loaded on the right hand reel and an empty ree I is placed on the left spind Ie. As the tape is moved from right to left during servo mode 1 it passes by a number of points which require different tension. As the tape is wound on the left hand reel, it starts winding on a small diameter since the reel is nearly empty. This means that the take up motor, if it were a fixed power or constant torque motor, would have a greater wind torque advantage when the reel was empty than when the reel was nearly fu II. To over come this effect of varying tape diameter I a variable torque motion is used which is controlled by the position of the tape tension sensing arm. This arm indicates to the motor when and how much tape to take up by means of a potentiometer attached to the arm which controls a dc servo. When the reader stepper motor drives tape toward the left reel, the tape sensor arm senses the slack in the tape causing the take-up motor to rotate counterclockwise. This takes the slack out of the tape and moves the sensor arm back to its mid-range.
Thus it can be seen that the tension applied to the tape by the sensor arm is the tension at which the tape passes the read head . The tape sensor arms are adjusted so that with the step'per motor stopped I the torque motor applies just the amount of tension to the tape required to hold the tape sensor arms in their approximate mid-position. Since the takeup and supply motors always return their arm to the mid-position, it is evident that the tension applied to the tape across the readhead is a function of the tape arm return spring tension.

NOTE
The frequency of cleaning as Hsted in TobIe 5-2 has been adopted for clean environmental conditions and usage. These items, however, may vary greatly from one installation to another. For example, a reader used in a machine shop to program numerical controls may require maintenance procedures considerably more frequently.
CLEANING
~ In all cleaning procedures, avoid usi.[lg cleaning methods and materials other than those recommended in this manual. Do not use ethyl alcohol or denatured alcohol as the d~naturjng agents vary and may damage the reader. Certa; n cleaning compounds will damage parts of the reader, especially in the readout assemb Iy area. REMEX primarily recommends the use of Mi Iler-Stephenson MS-200 Magneti c Tape Head Cleaner (REMEX Part Number 716004-150) for most areas requiring cleaning. However I due to the degreasing nature of the cleaner I it shou Id not be used in areas· where the spray may come in contact with bearings or other oil{;;d 12.9.W. This cleaner may be obtained from REMEX or directly from Miller-Stephenson Chemical Company at one of the fol lowing locations:
1001 East First Street Los Angeles, California 90012
Route 7
1350 W. Fullerton Avenue Chicago, Illinois 60614
Danbury, Connecticut 06810
To use the cleaner, hold the spray can 4 to 6 inches away from the area to be cleaned and allow spray to flush the dirt off. If a heavy buildup is present, loosen with the spray mist and scrub with a cotton swab. A 6-inch pin-point, spray nozzle extension is available for hard-to-reach areas or for delicate applications. Avoid spraying on lubricated surfaces or parts and on the lamp assemb ly and lens.
If the Miller-Stephenson cleaner is not available, a small amount of isopropyl alcohol applied to a clean, lint-free cloth or cotton swab may also be used. However, it should be used carefully and sparingly since damage to the photocell and the finish on the plastic cover may result. Use only clear, unadulterated isopropyl alcohol.

5.2.1.1 Readhead Assembly Cleaning
The top surface of the read head assembly should be cleaned every two weeks (for most installations having clean environments; dirtier environments which contain dust oil and sprays~ su~h as machin~ng areas, may require cleaning as much as every eight hours). Cleaning IS extremely Important because any dirt or foreign material in this area can create errors in readout. Use the bristle brush supplied or the cleaning materials and methods described in ~ectiori 5.2.1 and clean the surfaces of the readhead assembly and the upper tape gUIde assembly. Care should be exercised so that no residue remains from the recommended cleaning materials when the cleaning operation is completed. Figure 5-0 shows the brush inserted between the reodhead and tape guide when cleaning the the read head assembly. Pr:oper cJeaning requires_ that -the brush -be rotate<:J Ci~ leCist two . revolutions and moved in and out. Remove the residue with compressed air ..
5.2.1.2 Sprocket Cleaning
The sprocket wheel should be checked for cleanliness every two weeks. Depending upon tape conditions, accumulations may bui Id up 'on the sprocket and be transferred to the sprocket holes in the tape which may cause readout errors. Use the recommended cleaning materials described in the caution in Section 5.2. L Care should be taken so that the alignment of the sprocket wheel is not disturbed. If the sprocket wheel requires adjustment, refer to Section 5.4.
5.2.1.3 Tape Inspection
Repeated handling and usage of the tape leads to a build up of grease, oi I and dirt on the tape. When the build up becomes excessive, this material will become lod-ged in the tape transport areas and could cause tape reading errors. To prevent this, the tape should be thoroughly inspected every two weeks and repunched as required.
5.2.1.4 General Cleaning
The entire reader should be cleaned every year. Use the following procedure:
5.2.2
Using the bristle brush supplied with the unit and/or compressed air, remove all dust and dirt, paying particular attention to all moving parts. Use the recommended materials described in the caution in Section 5.2 to remove any grease or other accumulations. When cleaning, use care not to damage components on the circuit board.
LUBRICATION
Except tor the bearing shaft assembly, all points of rotation have permanentl~ lubricated bearings and should not require lubricat!on for the life of the part: Th.e beann~ s~ould be lubricated every six months by applYing one or two drops of cling 011 to the inSide surface of the bearing (part no. 112694-1).

5.4 READER ALIGNMENT
Proper operation depends upon making and maintaining accurate adjustments. Although all adjustments are mode at the factory, the following adjustments should be checked periodically (refer to Table 5-2) and should be performed only when the tope reader performance is unsatisfactory or when 'any of the following items is replaced: distributor, read head assembly, upper tope guide assembly, mechanism assembly, sprocket, step motor or circuit card. letter designations in parenthesis refer to items called out in Figure 7-1.
Improper adjustment of this procedure will result in one or both of the following problems: (1) Reading errors, especially in computer applications and (2) Restriction of the tope tolerances capable of being read , i.e., either long or short tolerance tapes, not the ±O.025 inch in either direction as specified in Section 3.6.
a.
b.
c.
1 1 2670-074A
~ This is a factory set adjustment and shou Id not require adjustment unless one of the aforementioned components has been replaced or the reader performance is unsatisfactory.
Remove all power and control signals by disconnecting PI and the power cord plug.
The procedure outlined in steps b through i should not be performed unless the read head assembly, mechanism assembly, sprocket or step motor has been replaced or the reader performance in unsatisfactory. Prior to adjustment, steps b, d, e and f shou ld be checked and corrective steps c and/or g, h, i and j performed only if necessary.
Remove the Upper Tape Guide. Check the clearance between the read head housing tape riding surface and the sprocket perimeter high point by placing the end of a small steel rule on the surface and rock the sprocket in both directions. See Figures 5-1 and 5-2 . Observe that the perimeter high point clears the steel rule by a few thousandths of an inch. The sprocket teeth must have maximum tope penetration with no interference when driving tape. If the sprocket is not positioned as described perform step c.
If the conditions of step It do not exist , loosen two screws (D) which hold the motor heat sink to the panel. Adjust the height of the motor so that the conditions in step b exist. Tighten screws (D). On some units it may also be necessary to loosen the four 8-32 socket head screws (B) at the rear of the pane I which hold the Mechanism Assembly to the Front Panel and move the Mechanism Assembly to achieve the required setting. This shou Id only be atte';1pted if the adius.tment ~annot be mode with the motor only. Tighten screws (B) If required. Ch.eck the conditions in step b again and perform step c as required.
5-9
5-10
L=:J If the motor has been running for a period of time it or the heat sink may be too hot to touch comfortably. Allow sufficient time for the motor and heat sink to cool before any adjustment or use a cloth or pair of gloves.
d. Insert a loop of tape known to have been punched to within :1:0.0025 inch in a 5-inch span (0.05% error).

NOif Since repeatability of the feedhole placement in either direction is essential, a tape whose accumu lated error in a 5-inch span is consider- . ably better than :1:0.025 inches (as specified- in Section 3.6) must be used in this procedure. Remex specifies a tape known to be punched to within :1:0.0025 inch in a 5-inch span (:1:0.05% tolerance). Note that most Remex punches are specified at :1:0.025 and therefore these tapes should not be used for this adjustment unless the tape has been checked on a reg istration gauge and found to be within :1:0.0025 inch.
Loosen nut (T) which holds the fiber optics light source to the reader pane I and rotate the light source away from the light tunne Is.
With the rear edge of the tape parallel to the front panel, align the holes over the light columns in the readout assembly so that they are concentric. See Figure 5-3. The tape must remain parallel to the front panel so that no skew is present. With the tape in this position, the sprocket teeth shou Id be centered in the sprocket holes in the tape. Skewing is indicated by tracks 1 and 8 not being concentric.
If the conditions of step f do not exist 1 loosen theJ:~o set screws (J) which hold the sprocket to the motor shaft and move the sprocket in orout on the shaft unti I the teeth are centered in the feed ho les and the tape holes remain concentric with the light tunnels. Tighten screws (J). Recheck the adjustment and readjust as required.
Connect the power plug and place the POWER switch into the ON position. The motor shou Id be energized.
loosen the single screw (S) which holds the motor to the heat sink (some earlier models may have two sets screws).
Rotate the motor so that the holes in the tape are concentric with the I ight co lumns in the read head and the sprocket teeth are centered in the feed holes. Tighten the set screws. Recheck the adjustment and readjust as required.
Remove the 0.05% tape .
Place the POWER switch in the OFF position.

m. Make sure jack screw (E) is not protruding below the surface of the Upper Tape Guide.
n. ~nsert three layers of 0.0037 mylar tape (approximately 0.011 Inch) stapled together at one end or a piece of 0.010 plastic shim stock (see Table 5-1) between the Upper Tape Guide and the Readhead Assembly.
o. Referring to Figure 5-4 use screws (H) and (N) to adjust the Upper Tape Guide so that there is maximum contact firm pressure on the tape, and parallelism from A to B. Use scr~ (H) for lateral movement and sc(ew (N) for rotational movement. From points B to C the Upper Tape Guide will not show this parallelism. '
p. Remove the three layers of tape.
q. Insert two layers of tape between points A and Bon Iy or a strip of 0.0075 shim stock.
r. Screw down jack screw (E) which will raise the Upper Tape Guide slightly. Adjust screw (E) until there is free movement of two layers ,of tape or shim stock between poi"ts A and B. This should provide a gap of between 0.009 and 0.011 inch.
s . Remove the two layers of tape or shim stock.
t. Connect P2 comin'g from the Readhead Assembly to a test circuit as shown in Figure 5-5. Connect a digital voltmeter in parallel with a 1 K resistor. Place the POWER switch in its ON position.
u. Adjust the lamp voltage to +4.3 Vdc. See Section 5.6 for lamp voltage adjustment. This is a preliminary step. The final lamp voltage is adjusted in step v.
v. The nut (T) holding the fiber optic light source to the front panel should already be loose (step e). Rotate the fiber optic light source until the current through the lK resistor is between 100 and 110 microamps for the sprocket cell. If the current is excessive reduce the lamp voltage. If the current is below the minimum requirements, loosen nut (U) which locks the lamp in the sleeve and screw the lamp in or out to obtain the required current. Tighten nut (U). If the current is still below the minimum requirement, increase the lamp voltage slightly to obtain the required current. Do not increase the lam2 voltage above +4.7 Vdc. When the required current is obtained for the sprocket, the minimum current for each of the data cells should be 80 microamps. The maximum output from any data cell should be 160 microamps so that tapes with the highest permitted transmissivity can be read without error.
w. Place the POWER switch in the OFF position and reconnect P2.
x. Place the POWER switch in the ON position and insert the 0.05% described in step d.
y. Connect a pulse counter to TP3 (Data Ready) and TP6 (OV) on the Reader Card.

z. Measure the drive left speed using a Dl * signal tied to OV at J.1-17. Repeat using a DR* signal tied to OV at J 1-16. If the lowest speed is more than 5% slower than the highest speed, loosen screw (5) which holds the motor to the heat sink. Rotate the motor slightly so that the difference in drive left and drive right speeds is less than 5%. Tighten screw (5). Repeat step z as required. When rotating the motor 1 make sure it is kept tight' to the panel so that the adjustment in stepg not disturbed. If steps 9 and i have been performed correctly only a slight adjustment of the motor shou Id be necessary to obtain the 5% difference in speeds.
NOTE The importance of steps y and z is not a specific interest in matching speeds, but rather that balancing speeds insures proper placement of the feedhole (via the sprocket) in re lation to its aperture in the reCldhead. The 0.05% tape used virtually assures that there are no feedhole placement errors which are attributable to tape registration errors, but only to the position of the sprocket in relation to the feedhole aperture in the readhead. Thus measuring and balancing the slew speed is only an accurate, electronic method of assuring that this re lationship exists. When the speeds in the two directions are properly balanced, feedhole placement error will be minimal and independent of the direction of the tape, thereby increasing tape readability to a maximum.

5.5 READER tAMP VOLTAGE ADJUSTMENT
The following procedure should be used when adjusting the readerfcimp ~o"tage:
5.6
a. Place the ON-OFF switch to its ON position. The reader lamp should come on.
b. Place a digital voltmeter across the lamp terminals.
c. Adjust R63 on the Reader card until the meter reads +4.3 ±O. 1 Vdc.
d . Remove the meter leads.
NOTE
The reader lamp voltage may require further adjustment to increase the photocell outputs. See Section 5.4, step v. Do not increase the voltage above +4.7 Vdc.
SERVO ALIGNMENT
Alignment of the servo system is performed' in the following manner:
a. Place the ON-:-.OFF switch in the OFF position.
b. Remove all tape and reels from the reader-spooler.
c . Place the SPOOL-LOOP switch in SPOOL and the OFF-ON switch in ON and place the RUN-LOAD switch in RUN position! . .
d. Rotate the left and right tape sensing arms to the center of their travel arc. Secure the arms in this position with a rubber band loop around the tape rollers.
e. If the left motor rotates when the arm is positioned in the center of its trave I arc I perform steps f and g.
f. Loosen the set screw which holds the coupling to the potentiometer shaft .
g . Rotate the shaft of the potentiometer unti I the left motor stops rotating. Tighten set screw (A).
h. Repeat steps e,f and g for the right arm.
5.7 ARM SPRING TENS ION ADJUSTMENT
Tension of the tape sensing arm spring is measured at the roller on the end of the arm.
a. Place the OFF-ON switch in the OFF position.
b. Attach a tension gauge to the tape arm ro Iler on the left arm using a piece of tape around the roller.
c. Pu" on the gauge perpend i cu lady to the tape arm and I ift the arm up off the outer stop. Note the gauge reading which should be between 4 and 5 ounces. Do not allow the tension of the arm on the switch to interfere with the measurements.
112670-074A 5-15
d. If the tension measurements do not agree with the specifications noted in step c, adjust the screw holding the arm spring up or down in the slotway until the conditions of step c is met.
e. Repeat steps b through d for the right arm.
5.8 SPOOLER TAPE ARM AND ROLLER ALIGNMENT
The tape rollers and the arm rollers should be positioned so that paper tape moves through the drive mechanism flat in either direction, without wave. Mylar tape may have a slight wave. All tape shou Id run through The head without excessive edge guiding, preferably with a slight tendency of guiding toward the panel.
To accomplish this alignment, a small amount of bending at the end of the tape arm may be required. However I the arm itself must be parallel to the pane lover its entire length. In addition, the distance from the front surface of the arm to the inside edge of the roller must be between O. 190 and 0.205 inch. This is improtant when a new roller has been installed and is accomplished by placing 1 or 2 713600-149 washers between the spacer and roller as shown in Figure 6-1 and as described in Section 6.3.4. The roller must also remain perpendicular to the front panel.
5.9 TAPE SPLICING
If tape breakage occurs, this break may result in damage to one, two or possibly three characters. When spiicing tape for this reader, great care shou Id be used to ensure that the proper sprocket hole spacing be preserved. A lap splice should not be used; use only a butt type splice. To repair the tape without loss of characters, the process shown in Figure 5-6·1s recommended and is accomplished as follows:
5-16
a. Bring the tape ends together as shown in Figure 5-6A.
b. Make a sketch of character(s) at the break (A-B-C) and five additional characters to the left (5-4-3-2-1) and five to the right (1-2-3-4-5) of the broken character{s) (A-B-C).
c. Place the left end of the broken tape over a section of blank tape containing only feed holes so that at least eight or ten feed holes in each tape are aligned with one another as shown in Figure 5-6B. Cut the tapes at the third undamaged character (A-B-C). Use care to insure that feed holes are aligned and make cut through the center of th~ ho les in the thi rd undamaged character. Characters 5, 4 and ha If of 3 should remain on the broken tape.
d. Place the right end of the broken tape over the section of blank tape so that at least eight or ten feed holes are aligned with one another. Feed holes for one-half of 3, 2 and 1 on the blank tape cut in sfep c should be visible to the left of the broken tape end as shown in Figure 5-6C. Cut the tapes at the third undamaged character to the right of the damaged character. Be sure that feed holes are aligned and make the cut through the center of the holes in the third undamaged character.
NOTE
One ha If of character 3 and characters 4 and 5 shou Id remain in the broken tape.
112670-074A
e. Place tape ends and new sectjQ£}on a flat surface with feed holes forward as shown in Figure ~6D_ (tape is bottom side up). Using . silver Scotch tape, No. 852, splice the new section and the old tape ends as shown. That portionof tape that secures the old tape ends must cover the first two and a half characters (one-half of of 3, 4 and 5) on the old tape ends. The edges of the tape shou Id be between characters as shown. Use of 1/2-:-inch wide splicing tape is recommended as shown in Figure 5-60.
f. Repunch the characters recorded in step d.

PARTS LIS T
7 . 1 GENERAL
Listed in Table 7-2 are the elec;tronic and mechanical parts used in the RRS7200BEX. Standard hardware items are not listed. Indented items are part of the assembly under which they are indented and the quantity of these items are per each assembly. Table 7-1 lists the recommended spare parts and the quantity column denotes the number recommended. Figures 7-1 through 7-4 illustrate the parts listed in Table 7-2. Those items identified by a broken arrow indicate the approximate location of parts not visible in the photograph.
Reference designations refer to the parts illustrated in Figures 7-1 through 7-4 (circled number designations in Figure 7.1; letter designations in Figure 7-1 refer to hardware items referenced in Sections 5 and 6). The reference designations include a figure number and a part designation number which appear on that figure to indicate the location of the part. For example, a 7-1; 12 appearing in the reference designation column indicates that the item listed in the description column can be located in Figure 7-1, Item 12. All electronic components are identified by letter-number combinations (such as S 1 and Tl) in the Reference Designation column and mechanical parts are identified by number. Refere~ce designations contained in parenthesis are associated or function with the parenthical item. These items are generally individual items and are not part of an assembly but for reference are related back to the associated item. All items are available from Spares Order Desk, REMEX, 1733 Alton Street, P. O. Box C19533, Irvine, Califomia 92713.
Tab Ie 7-3 contains the components used on the reader card.
